Scenario
Alert emails from the UPS worked before, but stopped after mail relay certificate or TLS requirements changed.
Recommended Resolution Path
- Review the UPS firmware support for modern TLS and ciphers.
- Confirm the relay target, sender, and authentication method still match current mail policy.
- Test with a scoped relay if the appliance cannot meet full mailbox auth requirements.
- If the UPS is too old, document that limitation and move alerting upstream.
Technician Notes
Document what changed, what confirmed the fix, and whether the issue points to a broader standards gap worth addressing for the client.
